Vandaag 10 jaar geleden https://sailing-dulce.nl/home/article-4756 #PlanetNine #TabbysStar #MedischSpectrumTwente Donderdag 21-01-2016 Een wonderbaarlijke en verrassende ontdekking, de potentiële negende planeet in ons zonnestelsel. Nog door niemand gezien en indirect ontdekt door de baanschommelingen die hij veroorzaakt bij verre ijzige objecten in de Kuipergordel, ver buiten de baan van Pluto. Er worden steeds meer van die objecten gevonden, nogal eens zelfs dwergplaneten van het formaat van Pluto. Maar deze..

Breakthrough! Astronomers Narrow Down Planet Nine

The hunt for the elusive "Planet Nine" is heating up as new orbital data allows researchers to pin down its potential location in our outer solar system.

In a few days the #PlanetNine hypothesis - first published on 20 Jan 2016 in the paper https://iopscience.iop.org/article/10.3847/0004-6256/151/2/22 ("EVIDENCE FOR A DISTANT GIANT PLANET IN THE SOLAR SYSTEM", yes, they shouted it in all caps) - will turn 10 years old. The proposed big outer solar system inhabitant has never been found: https://www.skyatnightmagazine.com/space-science/planet-9-x-y-edge-of-solar-system reviews the situation.

I may have erred by an order of magnitude Planet 9 would be about 50 -70 meters, not 500 meters at one AU at 10 cm scale. The outer edge of the Kuiper Belt would be 5 meters, and Neptune sized planet about ten times further at 50 meters.

And I also erred (automated technotypo) in posting only one cm per AU in the first post, I meant, and thought I had typed a scale of, ONE CM EQUALS ONE AU (the average distance from sun to earth)

I edited corrected both previous posts.

At 1 AU per 10 cm scale, with sun at edge of paper, Mercury thru Mars distance would fit on a sheet of letter sized paper, 11 inch ~ 28 cm. Jupiter half a meter away, Saturn nearly a full meter, Uranus two meters, Neptune 3 meters. Then the Kuiper Belt and Pluto 3-5 meters.

Planet X 10 times further than Jupiter approximately 50 70 meters, or 164 -230 feet, 77 yds from the Sun.
The largest object, the Sun, would be 0.7mm like a dot from a fine tip marker.

Someone (?) posted a story about the gravitational influence of another Neptune sized gas giant influencing Kuiper Belt objects, with fairly recent James Webb Space Telescope data supporting that. (Similar newslink below)

Which sent me down a rabbit hole reducing the solar system to a scale of 1 AU to ten centimeters. (Next few posts. 1/?)

Astronomers Announce Evidence That Our Solar System Has Nine Planets Once Again

Astronomers may have uncovered a massive hidden planet far beyond Neptune, using decades-old infrared data. The object’s faint signal and strange motion suggest something big is lurking in the dark.

HAY UN GIGANTE ESCONDIDO EN NUESTRO SISTEMA SOLAR... Y AÚN NO LO VEMOS 🕵️‍♂️🪐
Parece increíble que en pleno siglo XXI no conozcamos todos los rincones de nuestra propia casa. Pero las matemáticas no mienten: algo masivo acecha en la oscuridad más allá de Plutón.
¿Qué está pasando allá afuera? Abrimos hilo sobre el misterioso Planeta Nueve. 👇🧵

Discovery of 2023 KQ14 Ammonite challenges models of outer solar system formation

Astronomers have identified a new distant object in the solar system's outer reaches, named 2023 KQ14 or Ammonite, belonging to the rare class of sednoids—trans-Neptunian bodies with orbits far beyond Neptune. Unlike the three previously known sednoids, Ammonite's orbit does not align with theirs, i... [More info]
